Question 2 (Multiple Choice Worth 2 points)

(03.01)

Which of the following expressions is the definition of the derivative of f(x) = cos(x) at the point (2, cos(2))?

limit as h goes to 0 of the quotient of the difference between the cosine of the quantity x plus h minus the cosine of x, and h
limit as h goes to 0 of the quotient of the difference between the cosine of the quantity 2 plus h minus the cosine of h, and h
limit as h goes to 0 of the quotient of the difference between the cosine of the quantity 2 plus h minus the cosine of 2, and h
limit as h goes to 0 of the quotient of the difference between the cosine of the quantity 2 plus h plus the cosine of 2, and h

Answer 5

do you know the general formula for the derivative?

Answer 6

lim h->0 of cos(x+h)-cos(x)/h
lim h->0 of cos(2+h)-cos(h)/h
lim h->0 of cos(2+h)-cos(2)/h
lim h->0 of cos (2+h) + cos(2)/h
